It looks like Canada is being pushed out. . .the existing NAFTA requires 62 per cent of autos to be made in the three; the Mexico-US requires 75 per cent in Mexico and the US.

“Canada is currently the ninth-largest auto producer in the world, and fourth largest auto exporter by value, producing 2.4 million vehicles and exporting $48.8 billion worth of vehicles in 2016. Canada’s highest rankings ever was second largest producer in the world between 1918 and 1923 and third after World War II.” – Wiki
